Diatomaceous earth soil? | Rollitup
Jan 16, 2010· I think u mean diatomite. DI Earth will usually be ground up to a fine powder. DO NOT USE POOL DI EARTH, use horticultural DI Earth for bug repellent or moisture uptake for the soil. Diffrent shit sometimes. If you want to grow in Diatomite, it can be used as a medium and some growers ONLY grow in Diatomite.
